Data analysis for decisions, defining UAT scope and scripts, and driving business acceptance.
3 questions in Business Analysis.
Plan UAT backwards from the business outcome rather than forwards from the specification, and have real users run real work on realistic data. If sign-off lands on the wrong thing, measure the gap against the original objective and raise it as a change with its own business case.
Usually both are correct and they are answering different questions, so stop comparing totals and reconcile down to the first point of divergence. Publish a bridge that explains the gap in named components, then have one definition made authoritative with a named owner instead of declaring a winner.
Convert the open defects into business consequence and volume rather than counts, construct a phased or partial cutover as a real third option, and give the steering group one explicit recommendation with the conditions that would change it. A date treated as fixed while exit criteria stay negotiable is the failure to name.
